Samarium iron nitrogen rare earth permanent magnet material is a new generation of rare earth permanent magnet material, and the industrialization process is continuing to accelerate.

Rare earth permanent magnet materials are permanent magnet materials containing rare earth metals that can maintain strong magnetism after magnetization. Based on these characteristics, they are in line with the development trend of miniaturization and lightweight of electronic products and are widely used in consumer electronics, automobiles, and rail tracks. It is widely used in transportation and other fields. At present, there are four generations of rare earth permanent magnet materials on the market, namely SmCo5 series materials, Sm2Co17 series magnets, neodymium iron boron (NdFeB) series magnetic materials, rare earth iron nitrogen (Re-Fe-N series) and rare earth iron carbon (Re -Fe-C series) magnetic materials.

Samarium iron nitrogen rare earth permanent magnet material is the most representative type of the fourth generation rare earth permanent magnet material. It refers to an alloy composed of rare earth elements and transition metals as the matrix, which is pressed and sintered by powder metallurgy method, and then charged with a magnetic field. Compared with the current mainstream NdFeB rare earth permanent magnet materials, the magnetic materials obtained after magnetization have higher anisotropic fields, dimensional accuracy, resistivity, and better oxidation resistance and corrosion resistance.

At the same time, the raw material of samarium iron nitride rare earth permanent magnet material is mainly samarium oxide, which is a material associated with neodymium in rare earth ores. It has been hoarded in large quantities due to low demand, and the current price is low. Therefore, samarium iron nitrogen rare earth permanent magnet materials also have the advantage of low raw material prices. In the future, under the background of rising prices of raw materials (neodymium oxide) for NdFeB rare earth permanent magnet materials, SmFeN rare earth permanent magnet materials are expected to achieve a competitive advantage over NdFeB materials. Accelerating replacement, it has been widely used in home appliances, automobiles, medical, communications, consumer electronics and other fields.

According to the“2023-2028 Samarium Iron Nitrogen Rare Earth Permanent Magnetic Materials Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center shows that my country’s demand for neodymium iron boron rare earth permanent magnet materials will exceed 250,000 tons in 2022, and samarium iron nitrogen rare earth permanent magnet materials, as its high-end ideal substitute, have broad market development space in the future.

Samarium iron nitrogen rare earth permanent magnet material is a new type of magnetic material. At present, its research and development is still in its early stages, and large-scale production and application have not yet occurred. my country’s samarium iron nitrogen rare earth permanent magnet material industry is in the exploratory stage. At this stage, there are Anhui Wanlang Magnetic Plastics, Ningxia Junci New Materials, Guangzhou Xinlaifu New Materials, Hangzhou Spinner Technology, Hangzhou Permanent Magnet Group, etc. Enterprises have entered the field of R&D and production of this material.

Among them, Xinlaifu is currently the one with the fastest R&D progress among domestic samarium iron nitrogen rare earth permanent magnet materials. The company has mastered the key production technology of this material and has the ability to produce small batches of samarium iron nitrogen magnetic powder. In addition, the samarium iron nitrogen rare earth permanent magnet material developed by Wanlang Magnetics is advancing as planned and has now entered the pilot stage; Hangzhou Permanent Magnet has applied for a number of patents related to samarium iron nitrogen rare earth permanent magnet materials, such as “a high permeability Method for preparing high-performance samarium iron nitrogen permanent magnet materials with nitrogen efficiency.” Industry analysts people said that in the future, as the research and development process of local enterprises continues to accelerate, my country’s samarium iron nitrogen rare earth will always be The industrialization of magnetic materials is just around the corner.
